I 1 MINIMIINIIIMMINIIIIIMMINIIIIIIMISM EXECUTIVE SUMMARY This scoping study was undertaken at the request of the Environment Agency, following expressions of concern from fishermen that some species of Ephemeroptera (mayflies) appear to have declined on the R.Wylye and on the upper reaches of the Hampshire Avon. The purpose of this scoping study is to provide a short scientific review of the mayfly fauna of southern chalk streams. • Forty nine species of mayflies are known to occur in Britain. The status of two additional species is uncertain. An appraisal of the R1VPACS III data-base yielded 42 high quality sites on southern chalk streams. Examination of the species lists for these sites confirmed that over 50% of the British species occur on southern chalk streams. Information is provided on the seasonal occurrence of the different species and their frequency of occurrence at the 42 sites. Between four and fifteen species of mayflies were recorded per site, with an arithmetic mean of 9.12 per site. The most species-rich sites (12 or more species) occurred between 10 and 50, km from stream source. They included sites on such well known rivers as the R. Frome (Dorset), R. lichen, R. Lambourn, Moors River (Dorset) and R.Test. The study includes information on the longitudinal occurrence of each species. The R1VPACS III data-set also includes information on the log, categories of abundance of each family of mayfly in spring, summer and autumn, based on the standard R1VPACS pond-net samples. This provides a useful general guide on whether a given family is scarcc, common or abundant in a given season. Members of the Baetidae were found to be important components of the mayfly fauna in spring, summer and autumn, but were particularly abundant at most sites in summer. Ephemerellidae were also very abundant at most sites in summer. Notes are provided on the flight period and life cycles of each species, as far as these are known The life cycles of some species show flexibility and some members of the Baetidae are capable of having several generations in a year. Hence, interpretation of the life cycle can pose problems Information on the habitats, habits and feeding behaviour of the larvae demonstrates that a wide variety of different habitats and food resources are exploited by mayfly larvae. A consideration of the potential impact of flow regime on larval populations suggests that if changes in the flow regime affect the habitats and food resources within a stream, then there are likely to be consequences for the mayfly fauna. However, different members of the mayfly fauna may respond in different ways, given their various adaptations. Low flows arc of particular interest at present, and several short term studies on chalk streams, together with one long-term study on the R.Lambourn in the 1970's, are starting to provide scientific data on the way in which different components of the VII mayfly fauna appear to respond to the discharge regime. Some provisional findings for the Baetidae, Ephemerellidae and Ephemeridae are given below. A nine-year study on the R. Lambourn provided evidence that in early June, densities of larvae in the Baetidae (which may have included up to six species) were low in drought years (-500 ni2) compared with some years with high discharge when densities were —5,000 1112. Densities of larvae in the Ephemerellidae (Ephemerella ignita only) were higher in the year following a drought. Densities of larvae in the Ephemeridae (Ephemera danica only) did not appear to be related to the prevailing discharge regime in the R. Lambourn. Instead, cool damp conditions during the period of flight activity in May/June of one year resulted in very low larval densities of the next generation in December of that year. Over the next three generations (at intervals of two years), larval densities increased progressively in the December following oviposition. Studies commissioned by the Environment Agency on a number of chalk stream sites first examined in the 1970's may soon provide further information on the response of mayflies to the flow regime. Some chalk streams may be subject to organic pollution as a result of sewage effluent, fish farm effluent or farm wastes. Low levels of organic enrichment may not have adverse effects on the mayfly fauna, but more severe cases of organic pollution will result in the progressive elimination of the more sensitive species.

  • Secondary Production of Paraleptophlebia (Ephemeroptera)
    SECONDARY PRODUCTION OF PARALEPTOPHLEBIA (EPHEMEROPTERA) WITHIN THREE NORTHERN CALIFORNIA COASTAL STREAMS by Sarah Beesley A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment Of the Requirements for the Degree Masters of Science In Natural Resources: Freshwater Fisheries November, 2006 ABSTRACT Secondary production of Paraleptophlebia (Ephemeroptera) within three northern California coastal streams Sarah Beesley Annual production was estimated for the mayfly genus Paraleptophlebia occupying riffle habitats of three coastal streams within the Prairie Creek watershed, California. Monthly invertebrate collections yielded 4,579 Paraleptophlebia nymphs: 1,786 from Prairie Creek, 1,738 from Boyes Creek and 1,055 from Streelow Creek. Paraleptophlebia populations in the three streams were presumed univoltine based on monthly size frequency distributions. Emergence appeared to occur from spring through fall with early instars present from late summer through spring. Models relating ln total length to ln dry mass and ln head width to ln dry mass were developed from fresh Prairie Creek Paraleptophlebia nymphs to estimate dry mass of preserved nymphs. Annual production estimates were 89.7 mg•m-2•yr-1 in Prairie Creek, 69.9 mg•m-2•yr-1 in Boyes Creek and 74.0 mg•m-2•yr-1 in Streelow Creek. Annual production to biomass ratios were 8.56 in Prairie Creek, 11.39 in Boyes Creek and 5.89 in Streelow Creek. Water temperature accumulation was monitored to assess whether differences in thermal regime existed among the three streams. Annual degree day totals were very similar among the streams with values from 3,447 in Streelow Creek, 3,473 in Prairie Creek, and 3,486 in Boyes Creek.

Here we present the first comprehensive study of Ephemeroptera in the tufa-depositing habitats of the Dinaric Karst. The study was conducted in Plitvice Lakes National Park monthly during a one-year period (2007–2008) in different types of habitats (springs, streams, mountainous rivers, tufa barriers). The aims of the study were to determine mayfly composition, abundance, spatial distribution and habitat preferences, and to examine the environmental factors important for the structuring of mayfly assemblages in Plitvice Lakes National Park. The mayfly fauna of tufa-depositing habitats was composed of 14 species (20 taxa). Water temperature, pH and ammonium concentration were the most important environmental variables explaining mayfly assemblages. Mayfly assemblages grouped according to habitat type. Generally, the most favourable habitat type was mountainous stream, tufa barriers were less favourable, and the least favourable were springs.

    insects Article The Imaginal Characters of Neoephemera projecta Showing Its Plesiomorphic Position and a New Genus Status in the Family (Ephemeroptera: Neoephemeridae) Zhenxing Ma and Changfa Zhou * College of Life Sciences, Nanjing Normal University, Nanjing 210023, China; [email protected] * Correspondence: [email protected]; Tel.: +86-139-5174-7595 Simple Summary: The phylogenetically problematic Neoephemeridae is a small family of the order Ephemeroptera, including four genera reported previously. They are genera Neoephemera (in Nearctic region), Ochernova (Central Asia), Leucorhoenanthus (West Palearctic) and Potamanthellus (East Palearctic and Oriental regions), which were geographically isolated until the Neoephemera projecta Zhou and Zheng, a species reported in 2001 from Southwestern China, connected them together. In this work, the imaginal stage and biology of Neoephemera projecta are first observed and described. Furthermore, a series of autapomorphies and plesiomorphies of it are recognized and discussed. Morphologically and biologically, this species is significantly different from other genera and deserves a new plesiomorphic position in the Family Neoephemeridae. Therefore, a new genus Pulchephemera gen. n. is established to reflect its primitive position and intermediate characters of two clades of the family. In addition, some shared characters of this new genus and the family Ephemeridae provide a new perspective or possibility on the phylogeny of Neoephemeridae within Citation: Ma, Z.; Zhou, C.
